""" Function to resize an image. The image will be resized to the given
size, while keeping the aspect ratios, and holes in the image will be
filled with transparent background. The image will not be stretched if
smaller than the expected size.
Steps of the resizing:
- Compute width and height if not specified.
- if avoid_if_small: if both image sizes are smaller than the requested
sizes, the original image is returned. This is used to avoid adding
transparent content around images that we do not want to alter but
just resize if too big. This is used for example when storing images
